Custom Signature AppearancesPersonalized signature appearances allow you to provide additional information about the signer, affiliations, or company. Home users often modify the default appearance as a matter of personal taste, while enterprise users are sometimes provided with a company-specific style and logo. All appearance data is stored in the appearances.acrodata file at%USER%Application DataAdobeAcrobat(version)Security.Every aspect of the visible appearance is subject to customization, and the options range from using logos, a replica of your handwritten signature, photos, images, and text. A typical appearance consists of three customizable components:. Signature: A graphic that identifies the signer on the left-hand side of the appearance, such as a photo or scanned signatures. Transparent backgrounds allow a watermark to be visible in the underlying layer.
Signature details: Signature data that appears to the right of the signature. Watermark or logo: An image that appears behind the signature. The default is the PDF logo.You can create any number of appearances ahead of time for later use, and the signing workflow allows you to select one from your library of appearances.
However, you can also select the default appearance created from your name or create one on-the-fly at signing time.When you sign a PDF file, the appearance becomes part of the signed document. It is not part of the actual, hashed signature. appearances.acrodata: Stores signature appearances.

What is an acrodata file?An acrodata file is a PDF file. Like any PDF file it’s composed of a header, a bunch of objects that contain stings and streams (in this case the streams are the appearance images), a cross reference table, and a trailer. If you change the extension to PDF and open the file in Acrobat, you’ll see each custom image on its own page; however, all you’ll see are the pictures.
By using a text editor, you can see other data that helps define the custom signature appearance. For example, and other bits and pieces that define the appearance.The file is loaded when it’s needed rather than on launch. For example, when user invokes the New(or Edit) signature appearances panel under Preferences and when the Sign Document dialog is called. It’s at that time that the PPKlite plug-in looks in the user’s Security folder for the file, and if it’s there, loads the appearance list so the user can select one to edit or apply.At signing time, the signature appearance is written into the PDF file and saved so that it gets signed along with all of the previously existing data. If you’ve chosen a custom appearance, that object was copied from the acrodata file and used to help create the signature object in the signed PDF file.For details about deploying custom appearance files for your enterprise, see www.adobe.com/go/acrobatwizard. Name: The name associated with the certificate. Date: The date signed.
Signature appearances can only display local (computer) time, and it will likely differ from that in the Date/Time tab on the Signature Properties dialog when a timestamp server is used. Location: The location associated with the identity configured in Acrobat. Reason: The reason for signing.
Distinguished name: A name with details such as country, organization, organizational unit, and so on. Labels: A label for each of the items above. For example, Reason.
